Application filed February 28, 1910. Serial No. 546,407.

To all whom it may concern:

Be it known that 1, JOHN M. SAUssnR, a citizen of the United States, residing at Osnaburg, in the county of Stark and State of Ohio, have invented a new and useful Door-Bolting Device, ofwhich the following is a specification.

This invention has reference to fastening devices for swinging doors, and the primary object of the invention is to provide a simple and efficient device by which the doors of barns and similar structures may be effectually held in either their closed or opened positions.

A further objectof the invention is to provide a device capable of accomplishing the stated results, which will be compactly arranged and easily operated, and of inexpensive construction.

The invention consists in certain novel features of the device illustrated in the accompanying drawings, which show pre ferred embodiments of my invention, all of which will be hereinafter first fully de scribed and then more particularly pointed out in the appended claims.

In the drawings, Figure is a side elevation of my invention, showing it applied to the inner sides of a pair of double barn doors. Fig. 2 is a horizontal section taken through the upper bolts, shown in Fig. 1. Fig. 3 is a horizontal section takenjust above the handle lever and showing one of the doors held in its opened position. Fig. 4 is a detail perspective view of one of the upper bolts. Fig. 5 is a detail perspective view of the handle lever. Fig. 6 is an elevation of a modification of the invention by which it is adapted to a single door. Fig. 7 is a horizontal section of the device shown in Fig. 6, and illustrating the door in its opened position by dotted lines. Fig. 8 is a detail perspective view of the device illustrated in Fig. 6. Fig. 9 is a detail plan view of a further modification.

The doors 1, shown in Fig. 1, may be of any preferred construction and, in their closed position, will have their free sides or edges close together so as to entirely cover the door opening in the barn or other building. These doors are hung by means of any convenient style of hinges to the side of the building, and a beam 2 will usually extend across the top of the door opening, as clearly shown in Fig. 1. On the under side of the said beam 2, at the center of the door opening, I secure a keeper block 3, and in the floor of the barn or in the door sill, if a sill be employed, I provide metallic sockets 4, the said keeper block 3 and sockets 4 being adapted to'be engaged by bolts when the door is closed, so as to hold the door in its closed position. The lower bolts 5, which engage the sockets 4, are arranged vertically in a suitable casing or bracket 6 secured on the door and are held normally toward the sockets so as to engage the same by springs 7 coiled around the bolts between a shoulder or pin 8 thereon and the upper end of the casing in which the bolt is mounted, as will be readily understood. The upper end of each bolt is engaged by a link 9 which extends upward to and is pivotally connected with a handle lever 10 which is fulcrumed between its ends upon the inner side of the door, as in dicated at 11, the link 9 being attached to the said handle lever near the front end thereof or that end which is nearer the free edge of the door. The inner end of the lever is connected, by a link 12, with a bell crank lever 13 mounted on the end of an arm 14, depending from one end of a bracket 15, which is secured to the inner side of the door near the upper end of the same, as clearly shown. This bell crank lever 13 is fulcrumed between its ends within a depending U-shaped portion 16 at the end of the arm 14, whereby the lever will be prevented from having lateral movement, so that it will be always in such a position as to operate easily and without binding. The arm 14 is offset from the bracket 15, and the central portion of the said bracket is offset to a similar extent from its ends, whereby a housing is provided for a locking bolt 16 which is slidably mounted in the ends of the bracket and adapted to engage the front side 17 of the keeper block 3, as shown clearly in Fig. 2. A spring 18 is coiled around the locking bolt 16* within the central part of the bracket and acts doors in their closed positions.

on the bolt so as to project the same normally outward in position to engage the front side of the keeper block 3, as will be readily understood. The inner end of the bolt is pivotally attached to an upstanding arm 19 of the bell crank lever 18, whereby the movement of the said lever will be transmitted directly to the bolt and the bolt moved in opposition to the spring. The lever 13 extends in both directions from its fulcrum and the end opposite that end to which the link 12 is connected is adapted to have suspended therefrom a weight 20, so that if the spring 18 should be broken or become too weak to project the bolt into engagement with the keeper block, the lever would be operated by the weight and the bolt thereby thrown.

The dooris provided with a slot 21 near its edge, and the handle lever 10 has its front end bent laterally, as shown at 22, and formed into a hook 23, which is adapted to engage a keeper or other retaining device 24 on the side of the barn, so that when the door is opened, as shown in Fig. 3, the said keeper 2 1, by its engagement with the hook 23, will hold the door against the side of the building so that it will not be closed by the action of the wind or by reason of any accidental blow imparted thereto. In order to lock the handle lever 10 against move ment, when it is desired to prevent the open ing of the doors, an eccentric or similar locking device 25 may be mounted on the inner side of the door adjacent the said handle lever and adapted to bear against the edge of the same so as to prevent the releasing movement thereof.

It is thought the operation and advantages of my device will be readily under stood from the foregoing description, taken in connection with the accompanying drawlngs.

WVhen the doors are closed, the upper bolts 16 and the lower bolts 5 will engage their respective sockets so as to hold the The laterally-bent hooked end of the handle or lever 10 will project through the door and will serve as a handle by which the lever may be vibrated upon its fulcrum so as to actuate the links 9 and 12, and thereby withdraw the bolts from their engagement with the sockets and, consequently, permit the opening of the door, it being understood that when the locking device 25 is employed, a suitable key will be provided to permit the moving of the said locking device from the outside of the door, in order to release the handle lever. WVhen the door has been opened, it will swing around to the side of the building and the hook 23 will automatically ride over into engagement with the keeper 2 1, as will be understood, the edge of the hook being beveled as indicated at 26 to facilitate this operation. lVhen the door is closed, the ends of the upper bolts will ride upon the beveled or tapered ends of the keeper block 8 and will be thereby pushed inward against the tension of the springs 18 so that they will automatically engage the sockets in the said keeper block.

It will be readily seen that the device is extremely simple in its construction and the arrangement of parts, and that a single element serves to release the locking bolts and also to perform the function of a handle to open the door, and also as a means for holding the door in its opened position.

lVhile the device has been shown in Figs. 1, 2 and 3, applied to double doors, its usefulness is not restricted to that application, and in Figs. 6, 7 and 8, I have shown a modification of the invention, in which it is.

further simplified and applied to a single door. In these figures, the bell crank lever has been omitted and the bracket 15 is secured to the inner side of the door adjacent the free edge of the same, at such a height as may be most convenient in practice, and the bolt 16 is arranged to engage a socket 27' in the side of the door jamb 28. The handle lever 10 is connected directly to the bolt instead of indirectly, as in the other figures, by being disposed vertically and having its lower end pivoted within the U- shaped portion 16 of the offset depending arm 14 of the bracket and having its hooked end projecting through a slot 29 which is arranged in the door above the bolt, the end of the bolt being engaged in the same opening of the handle lever which, in the preferred form of the invention, receives the fulcrum pin. An eccentric or similar locking device 30 is mounted 011 the door in position to bear against the rear edge of the lever so as to hold the same against movement when it is desired to lock the door. The operation of this form of the invention is the same, in all respects, as the form applied to the double doors, with the exception that the handle lever acts directly on the locking bolt, instead of indirectly through intermediate connections.

While I prefer to utilize the depending arm let as a fulcrum, this element may be dispensed with and the lever fulcrumed upon a small block on the side of the door and this latter arrangement will frequently be found more desirable on single doors. It will also be understood that the weights 20 and the eccentrics 25 may be omitted without departing from the invention or necessarily impairing the efliciency of the device.

In Fig. 9, I illustrate a further modification of the invention in its application to single doors. In this arrangement, the bracket is disposed with its main portion against the door and is secured thereto by bolts 31 inserted through said main portion or back and one end of the bracket is shaped to present a horizontal lug or car 82 to which the inner end of the lever handle 33 is fulcrumed. The lever is straight and lies in a horizontal plane and is pivoted at an intermediate point of its length to the end of the locking bolt 34. It will be noted that in this Fig. 9, I have omitted the beveled end of the lever and have shown a notch 35 in the edge thereof, it being intended to provide an inclined surface on the keeper provided on the side of the building over which the end of the lever may ride to engage the keeper.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claims appended hereto.
